Hidden Virus -- DDS log, Attach.txt and Ark.txt attached

Hi, and thanks for any help. Running VISTA OS. I am infected with a virus I cannot find (Hijack this, malwarebytes, exterminate this, AVG and microsoft windows malicious software removal tool). This virus does a redirect in my browser, and randomly shuts my computer down with a window saying:

"Windows has encountered a critical problem and will restart automatically in one minute"

As the screen is going black, there is another window which says:

"Your current security settings do not allow this file to download"

Then the computer reboots.

Here is the DDS log file, with the Attach.txt and ark.rxt attached. Again, thanks for any help.

After reading the DDS file, which indicated a possible TDL3 Rootkit infection, I googled on and found a program to eliminate this virus: TDSSKiller by Kaspersy. Running this found and -- so far (24 hours) -- has seemed to have eliminated the problem. Combofix needed me to uninstall AVG in order to work, and given my success (so far), I am reluctant to go through the trouble. However, if you think it wise to check with Combofix, I will uninstall AVG (it was not running, BTW), and post the resultant log file.

Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.

ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.

When finished, it shall produce a log for you.

Copy and paste the contents of the log in your next reply.

CAUTION:Do not mouse-click ComboFix's window while it is running. That may cause it to stall.

Please open your MalwareBytes AntiMalware Program

Click the Update Tab and search for updates

If an update is found, it will download and install the latest version.

Once the program has loaded, select "Perform Quick Scan", then click Scan.

The scan may take some time to finish, so please be patient.

When the scan is complete, click OK, then Show Results to view the results.

Make sure that everything is checked, and clickRemove Selected. <-- very important

When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. (See Extra Note)

The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.

Copy&Paste the entire report in your next reply.

Extra Note:If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts, click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.

Then from your desktop double-click on jre-6u23-windows-i586-p.exe to install the newest version.

After the install is complete, go back to your Control Panel(using Classic View) and click the Java icon. (looks like a coffee cup)

On the General tab, under Temporary Internet Files, click the Settings button.

Next, click on the Delete Files button.

There are two options in the window to clear the cache - Leave BOTH Checked

Applications and Applets

Trace and Log Files

Click OK on Delete Temporary Files Window. Note: This deletes ALL the Downloaded Applications and Applets from the CACHE

Click OK to leave the Temporary Files Window.

Click OK to leave the Java Control Panel.

P2P - I see you have P2P software BitTorrent installed on your machine. We are not here to pass judgment on file-sharing as a concept. However, we will warn you that engaging in this activity and having this kind of software installed on your machine will always make you more susceptible to re-infections. It may be contributing to your current situation. This page will give you further information. Please note: Even if you are using a "safe" P2P program, it is only the program that is safe. You will be sharing files from uncertified sources, and these are often infected. The bad guys use P2P filesharing as a major conduit to spread their wares.Please see this topic for more information:Perils of P2P File Sharing.I would strongly recommend that you uninstall these now. You can do so via Control Panel >> Add or Remove Programs.

Just some house keeping to do now. You can re-install AVG if you wish, or if you would prefer to try another AV, then I recommend Microsoft Security Essentials, it's excellent and free - Avira and Avast asre also really good. Try them out one by one, see which you prefer (don't install more than one antivirus)

Keep Windows updated by regularly checking their website at :http://windowsupdate.microsoft.com/
This will ensure your computer has always the latest security updates available installed on your computer.

Make Internet Explorer more secure

Click Start > Run

Type Inetcpl.cpl & click OK

In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".

Next Click OK, then Apply button and then OK to exit the Internet Properties page.

It's normal after running TFC cleaner that the PC will be slower to boot the first time.

Keep a backup of your important files - Now, more than ever, it's especially important to protect your digital files and memories. This article is full of good information on alternatives for home backup solutions.

ERUNT (Emergency Recovery Utility NT) allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed.
